[Trac] Custom forbidden page

[Markus Tacker]

Is there a way to display a wiki page below the
> WIKI_VIEW privileges are required to perform this operation
message?

Reason I am asking is, I have a private wiki and anonymous has no
rights at all. But I want to tell anonymous to register and get in contact
with us.
